1. Characterization of the Mechanisms of Drug Release from Polymer-Coated Formulations using Experiments and Modelling
Abstract : The main objectives of the work presented in this thesis were to develop new experimental methods to improve the understanding of the release mechanism from a coated formulation and to develop new mechanistic models to describe the release process for pellets coated with a semi-permeable film. Another aim was to characterize the release mechanism from a formulation coated with films made of a blend of a water-insoluble polymer, ethyl cellulose (EC), and a water-soluble polymer, hydroxypropyl cellulose (HPC).

2. Ethyl Cellulose Membranes used in Modified Release Formulations
Abstract : Ethyl cellulose (EC) is a commonly used polymer in modified drug release formulations. The general aim of the present study was to investigate release mechanisms through non-porous EC membranes with hydroxypropyl methyl cellulose (HPMC) contents ranging from 0 to 30% by weight. READ MORE
